Emilio Guerrero released a new version of his CCZ80 compiler which understands C style code and is aimed for Z80 CPUs (thanks for your message here!).

Here are the new features / bugfixes of the new version:

• New option in compiler /include for specify paths to search include files in program.
• Allow use labels with the operators == and !=.
